Broken NFS after 9-26

On 9-26 installed update packages on a RH6 file server. The server host multiple network drives to Solaris and other RedHat machines. After the patches were applied, uses are no longer able to use svn or tar commands on the Solaris machines on data which lives the RedHat systems. The Solaries machine also supports a ADA Multi Complier it is no longer able to populate the file and folders in the file browser for the application. These applications were working without issues prior to the 9-26 updates. The problem appears something has changed with NFS. I can provide addition details if someone is having a similar problem. Thanks
